About wi-fi streaming

How do I start Wi-Fi streaming?

Download the KEF LS50 Wireless app from the Specifications tab and follow the step-by-step instructions.

What router should I use?

For better streaming stability, you are recommended to have a dual-band router. Streaming Hi-Res music files through a 5GHz Wi-Fi network with a router transmission speed of at least 1300Mbps will offer better performance. Below are detailed technical requirements.

Your wireless router must support IEEE 802.11a/b/g/n.

Security protocol WPA2, mixed mode WPA2/WPA, WEP and open networks. Open networks are not recommended for security reasons.

WEP is an old encryption and may lead to setup and streaming problems. The WPA2 security protocol is recommended. Please refer to the user guide of your router to select the encryption method.

Channel 1-11 (2.4GHz) and Channel 36, 40, 44, 48 (5.2GHz) or Channel 149, 153, 157, 161, 165 (5.8GHz, in Tai Wan ONLY) are supported. You are recommended to set the router on a channel with fewer overlapping networks as this will have less interference. Please refer to the user guide of your router to select the router channel.

How do I rename my speaker?

You can do it in the KEF LS50 Wireless app.

Tap “Settings” > “My speakers”

Select your speaker and tap “Speaker name” to change the name.

How do I connect the speaker to a new network?

Do a “Factory reset” to connect the speaker to a new router network.

1. Press a paperclip or a small Allen key on the “Reset” button in the back panel

2. Release the pin when the blinking green light goes solid

3. Shortly after, you will see the Wi-Fi signal light alternate between blinking red and white. You can now do the network setup again.

4. Go to “LS50 Wireless App”, select “Setup new speaker”

How do I improve streaming stability?

1. We recommend streaming Hi-Res music files over a 5GHz Wi-Fi network with a router transmission speed of at least 1300Mbps.

2. Signal interference from nearby Wi-Fi devices can weaken music streaming stability. Try using a Wi-Fi analyser app to analyse signal strength and look for a better signal channel. For details, please refer to the user manual of your router.

3. Wi-Fi signals in different home environments vary. Speakers and mobile devices are recommended to be placed in an area with a good Wi-Fi signal.

4. Minor interruptions during streaming are normal when there is a weak Wi-Fi signal or heavy network traffic.

5. A heavy streaming workload due to other Wi-Fi devices in the home is one of the common reasons for this issue. To maintain quality streaming, avoid downloading or uploading files during music streaming.

Why is my wireless streaming sometimes interrupted?

Minor interruptions during streaming are normal, especially when there is a weak Wi-Fi signal or heavy network traffic. A heavy streaming workload due to other Wi-Fi devices in the home is one of the common reasons for this issue. To maintain playback quality, we recommend avoiding downloading and uploading files during music streaming.

Signal interference from other nearby Wi-Fi devices can also weaken music streaming stability. If this happens frequently, try using a Wi-Fi analyser app to detect the signal strength and look for a better signal channel. For details, please refer to the user manual of your router.

My initial setup failed, and a red Wi-Fi icon has appeared. What should I do?

If the setup failed and you see the red Wi-Fi icon, please reset the speaker and try again.

Please follow these instructions and troubleshoot using the “LS50 Wireless App”:

1. Press a paperclip or a small Allen key on the “Reset” button in the back panel

2. Release the pin when the blinking green light goes solid

3. Shortly after, you will see the Wi-Fi signal light alternate between blinking red and white. You can now do the network setup again

4. If problems persist, please contact your local dealer or service centre.

I see a solid white Wi-Fi icon on LS50 Wireless, but my App cannot discover the speaker.

Please follow the below instructions to resolve this:

1. Restart the app

2. If you have another DLNA controller app, see if LS50 Wireless appears in that app

3. Restart the speaker

4. Reset the speaker and repeat the initial setup

5. If problems persist, please contact your local dealer or service centre

LS50 Wireless is connected, but streaming does not start.

Streaming requires more time to buffer when compared to local music playback, and Hi-Res music files are significantly larger. Please be patient when streaming Hi-Res music.

1. Ensure the speaker is connected to a network, as indicated by a solid white Wi-Fi icon

2. Ensure the app is connected to the speaker

3. Wait a moment after selecting a song to play, especially if selecting a Hi-Res music file

4. Avoid sending too many commands at once

5. If problems persist, restart the app

6. Restart the speaker

7. Reset the speaker and repeat the initial setup

8. If problems persist, please contact your local dealer or service centre

about the remote control

Why does the remote control not respond?

There are several possible reasons:

Make sure you have removed the battery protection from a new remote control. Turn the remote control over and look at the back. You will see a thin transparent film under the battery. Pull it out before use.

Your remote control may have run out of battery. Take off the battery door and replace the used battery with a new CR2032 3V battery.

Make sure there are no obstacles between the signal sensor on the “Right” speaker and the remote control.

Make sure the remote control is within the normal working range, which is around 5m from the speaker.

My remote control is not as sensitive as before. What can I do?

It is very likely you need a new battery. Please take off the battery door and replace the used battery with a new CR2032 3V battery.

What battery is used on my remote control?

A CR2032 3V battery.

Can I use all functions in all playback modes?

Play/Pause, Next and Previous are not available in AUX and Optical mode.

For better streaming stability, you are recommended to have a dual-band router. Streaming Hi-Res music files through a 5GHz Wi-Fi network with a router transmission speed of at least 1300Mbps will offer better performance. Below are detailed technical requirements.

Your wireless router must support IEEE 802.11a/b/g/n.

Security protocol WPA2, mixed mode WPA2/WPA, WEP and open networks. Open networks are not recommended for security reasons.

WEP is an old encryption and may lead to setup and streaming problems. The WPA2 security protocol is recommended. Please refer to the user guide of your router to select the encryption method.

Channel 1-11 (2.4GHz) and Channel 36, 40, 44, 48 (5.2GHz) or Channel 149, 153, 157, 161, 165 (5.8GHz, in Tai Wan ONLY) are supported. You are recommended to set the router on a channel with fewer overlapping networks as this will have less interference. Please refer to the user guide of your router to select the router channel.

How do I rename my speaker?

You can do it in the KEF LS50 Wireless app.

Tap “Settings” > “My speakers”

Select your speaker and tap “Speaker name” to change the name.

How do I connect the speaker to a new network?

Do a “Factory reset” to connect the speaker to a new router network.

1. Press a paperclip or a small Allen key on the “Reset” button in the back panel

2. Release the pin when the blinking green light goes solid

3. Shortly after, you will see the Wi-Fi signal light alternate between blinking red and white. You can now do the network setup again.

4. Go to “LS50 Wireless App”, select “Setup new speaker”

How do I improve streaming stability?

1. We recommend streaming Hi-Res music files over a 5GHz Wi-Fi network with a router transmission speed of at least 1300Mbps.

2. Signal interference from nearby Wi-Fi devices can weaken music streaming stability. Try using a Wi-Fi analyser app to analyse signal strength and look for a better signal channel. For details, please refer to the user manual of your router.

3. Wi-Fi signals in different home environments vary. Speakers and mobile devices are recommended to be placed in an area with a good Wi-Fi signal.

4. Minor interruptions during streaming are normal when there is a weak Wi-Fi signal or heavy network traffic.

5. A heavy streaming workload due to other Wi-Fi devices in the home is one of the common reasons for this issue. To maintain quality streaming, avoid downloading or uploading files during music streaming.

Why is my wireless streaming sometimes interrupted?

Minor interruptions during streaming are normal, especially when there is a weak Wi-Fi signal or heavy network traffic. A heavy streaming workload due to other Wi-Fi devices in the home is one of the common reasons for this issue. To maintain playback quality, we recommend avoiding downloading and uploading files during music streaming.

Signal interference from other nearby Wi-Fi devices can also weaken music streaming stability. If this happens frequently, try using a Wi-Fi analyser app to detect the signal strength and look for a better signal channel. For details, please refer to the user manual of your router.

My initial setup failed, and a red Wi-Fi icon has appeared. What should I do?

If the setup failed and you see the red Wi-Fi icon, please reset the speaker and try again.

Please follow these instructions and troubleshoot using the “LS50 Wireless App”:

1. Press a paperclip or a small Allen key on the “Reset” button in the back panel

2. Release the pin when the blinking green light goes solid

3. Shortly after, you will see the Wi-Fi signal light alternate between blinking red and white. You can now do the network setup again

4. If problems persist, please contact your local dealer or service centre.

I see a solid white Wi-Fi icon on LS50 Wireless, but my App cannot discover the speaker.

Please follow the below instructions to resolve this:

1. Restart the app

2. If you have another DLNA controller app, see if LS50 Wireless appears in that app

3. Restart the speaker

4. Reset the speaker and repeat the initial setup

5. If problems persist, please contact your local dealer or service centre

LS50 Wireless is connected, but streaming does not start.

Streaming requires more time to buffer when compared to local music playback, and Hi-Res music files are significantly larger. Please be patient when streaming Hi-Res music.

1. Ensure the speaker is connected to a network, as indicated by a solid white Wi-Fi icon

2. Ensure the app is connected to the speaker

3. Wait a moment after selecting a song to play, especially if selecting a Hi-Res music file

4. Avoid sending too many commands at once

5. If problems persist, restart the app

6. Restart the speaker

7. Reset the speaker and repeat the initial setup

8. If problems persist, please contact your local dealer or service centre

about the remote control

Why does the remote control not respond?

There are several possible reasons:

Make sure you have removed the battery protection from a new remote control. Turn the remote control over and look at the back. You will see a thin transparent film under the battery. Pull it out before use.

Your remote control may have run out of battery. Take off the battery door and replace the used battery with a new CR2032 3V battery.

Make sure there are no obstacles between the signal sensor on the “Right” speaker and the remote control.

Make sure the remote control is within the normal working range, which is around 5m from the speaker.

My remote control is not as sensitive as before. What can I do?

It is very likely you need a new battery. Please take off the battery door and replace the used battery with a new CR2032 3V battery.

What battery is used on my remote control?
